Problems solved by technology

[0004] Most of the existing light-transmitting surfaces are flat. On the one hand, it is difficult to attach the pollutants to be detected. On the other hand, with the change of the thickness of the pollutants, the amount of light reflected by the attachments on the light-transmitting surface changes little. Therefore, the detection is accurate. low degree

Abstract

The invention discloses a lens assembly, a device for detecting the attachment magnitude and a household appliance. The lens assembly comprises a lens and a surface mesh part and is arranged on the device for detecting the attachment magnitude; a light transmitting surface is arranged on one side of the lens, and an incident surface and an emergent surface are arranged on the other side of the lens; the surface mesh part and the light transmitting surface are spaced with each other and are oppositely arranged, and a plurality of meshes are formed in the surface mesh part. The lens assembly disclosed by the invention is easy to sample and can increase the scope of the quantity of light reflected by attachments.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a lens assembly, a device for detecting the value of attached matter and household appliances. Background technique [0002] At present, for electrical appliances or components of electrical appliances exposed to oily fumes, the surface in contact with the oily fumes will accumulate a layer of pollutants over time, such as liquid viscous oil stains. These pollutants may affect the performance of electrical appliances or electrical components, or deteriorate the hygienic environment of electrical appliances or electrical components. Therefore, it is necessary to propose a device for sampling and detecting these pollutants, so as to remind the user to clean or make the electric appliance itself automatically trigger the cleaning procedure accordingly. [0003] A photoelectric device used to detect the amount of attached matter generally includes a lens and a number of...
